Sound like something may have dropped into cylinder head. Hard one to check. Do a compression check on cylinders.

Sound inside the engine


Does the knocking sound increase with engine speed? Check all the things run by the belts, like A/C, alternator, etc. by removing the belts and starting the engine. If there is no more knocking, then check those components. If the knocking is still, you may have an internal engine problem like main or rod bearing failures. Check the engine oil for any metal flakes.

Try changing the fuel filter. If that does not help, have someone test the injector pump for pressure. Last would be a compression test on the cylinders. Drain oil and replace oil filter very soon.

What has happened is the diesel fuel is a lubricant and gasoline is a solvent. As gasoline is much thinner, it could wash down the cylinders and get into the oil pan thinning the oil and ruining the bearings. This would be the reason to test the pressure in the cylinders to find out if you lost compression with the rings in the cylinders.

Next, the injector pump for the diesel has seals and tolerances for inside components. Again, since gasoline is a solvent and not a lubricant, the internal parts could be worn out by not having diesel fuel to lubricate the injector pump parts.

If someone working at the fuel station made this mistake, all the costs should be paid by the station. This is something which could be taken to court if the station does not pay.

Why is my 97 Nissan pu still trying to stall after they diagnosed it with a bad mass air flow sensor, replaced and it is still trying to stall AND the check engine light came back on?


Most of us know how the injectors get clogged. Its nothing else but the fuel that we use which causes clogging. Every time we turn off our car's engine, last drop of petrol dries on the nozzle of the injector and leaves behind deposits. These deposits become firm with the heat of the chamber. The more we drive our car, more deposits accumulate. Gradually it starts to restrict the flow of petrol from the tiny hole on the nozzle and the injector starts to lose its efficiency. This causes the engine to lean misfire and hesitate on different rpm, power and pickup is lost, the car becomes uneconomical on petrol, unburnt fuel can be noticed in the emission and worst of all the wear of engine becomes faster. Only 8% to 10 % clogging in the nozzle can cause all this



Proper cleaning can restore their like-new performance. There is no need to replace fuel injectors unless they are actually gone bad. Injectors are designed in such a way that they are not very convenient to clean. They are sealed units and cannot be opened for cleaning. Ultrasonic cleaning is MOST effective process for cleaning fuel injectors. It is cheap and comprehensive solution for the problem.

YOUR FUEL INJECTORS HAS TO BE PRESSURE CLEAN IF YOU HAVE PETROL ENGINE.BEST TO LET GARAGE CLEAN INJECTORS.YOUR POWER LOST PROBLEM COULD BE FAULTY TURBOCHARGER OR WASTEGATE ALSO CHECK FOR RESTRICTED EXHAUST MUFFLER OR CATALYTIC CONVERTER.

Dear dsmalley427,
I think it sounds like a fuel injection problem. You get fuel for a while until the injector backs up and then all of a sudden NO FUEL. The engine quits and the pressure drops and flow returns enough for you to restart. If I were you I would get to a good mechanic and check the fuel injectors.
OR--try adding a fuel additive that would clean the injectors.--Signed jwr
